Hi Jeff!
Thank you for your help, this time I successfully compiled LAM with IMPI
support from the snapshot version. However, It keeps with the same error
I found on LAM 7.0.4, the "truncation of socket" problem.
The application is a simple HelloWorld, but this error also occurs when
the application has only MPI_Init and MPI_Finalize. Do you have an idea
on why this happens, and if this error can be corrected in the next
versions (in the next snapshot, for example ;) ?
Below you can find the output from the server and the clients. I also
added the full (-v) output from the server at the end of this email. I
hope these outputs can help you.
Thank you, and have a Happy New Year :)
